Benefits of technology

The present invention is a system that can receive and distribute multiple types of stream data to terminal devices. The system selects information with high priority based on user requests and distributes it to the terminal devices within a limited data transmission band. The system can also store unselected information into a file device for later viewing. The invention allows users to conveniently and automatically receive information with high priority and ensures continuous and appropriate band distribution without requiring complex procedures. The technical effects of the invention include efficient information delivery and improved user experience.

Problems solved by technology

However, the picture quality at attending the stream relatively becomes low when the band is narrow.
To attend the stream which the user demands by the high picture quality, it is necessary to reset the band of the corresponding stream, but the operation procedure is complex.

(Application Example of the Embodiment)

[0075]Hereafter, an operation of the stream distribution server when this embodiment is applied to a concrete example will be explained.

(Broadcasting Attention)

[0076]A case where the terminal device A puts out the attention request of a program X is assumed, now. Where, the program X is constructed with the data of the packet identifiers pid1, pid2, and pid3.

[0077]The contents information manager 27 in the stream distribution server 2 manages the program information, and has information to specify whether each program is constructed with the data of which packet identifier. The local area network manager 21 in the stream distribution server 2 receives the attention and recording request, etc. from the terminal device A, and performs the setting of the stream multiplexer-demultiplexer 20 and the stream filter 26. The local area network manager 21 monitors the local area network, and performs the band setting of the stream filter 26 if necessary....

Abstract

A stream distribution system comprises a stream distribution server, a plurality of terminal devices each having a information reproduction function, and a local area network for connecting both of the stream distribution server and the terminal devices, in which the stream distribution server comprises reception means for receiving a stream data of a digital form transmitted through a broadcasting network or a communication network, selection means for selecting a predetermined unit of information from the stream data received by the reception means based on a distribution condition set by the terminal device which has an information reproduction function, file I / O means for controlling a file device under management of the stream distribution server and for outputting information selected by the selection means to the file device, and transmission means for transmitting information selected by the selection means to the terminal device after executing a predetermined processing according to a limitation of a preset data transmission band.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to an information delivery system for delivering digital information transmitted through a broadcasting network or a communication network to a plurality of terminal devices, especially, to a stream distribution system which handles stream data.[0002]In recent years, due to the spread of the digital broadcasting network and the communication network (including a computer network) which includes digital satellite broadcasting and CATV, etc., a so-called information delivery system is proposed to provide various information, that is, multimedia information to many and unspecified homes (hereafter, called a user). Here, multimedia information means digital information on the video, the static image, and the voice, etc. In this digital information, information, which especially includes a video, a voice, a static image, and character information, etc., and requires a real time characteristic, is called stream data. This stre...
